Description

Technical Field

[0001] This utility model relates to the field of cartridge-type oil separators, and more particularly to a cartridge-type dynamic monitoring oil separator. Background Technology

[0002] In modern industry, grease, commonly known as butter, is a semi-solid lubricant made by adding thickeners and various additives to base oil. It is widely used for the lubrication and protection of friction pairs such as bearings, gears, and guide rails in industrial equipment. Centralized lubrication systems are crucial for ensuring the bearings and guide rails of large machinery and production lines. As the terminal actuator of the system, the oil distributor is responsible for accurately and evenly distributing the pumped grease to each lubrication point. The accuracy and reliability of its operation are directly related to the lifespan of the equipment and production safety.

[0003] The existing cartridge-type dynamic monitoring oil separator cannot meet the dynamic oil supply demand. Moreover, it is difficult to make rapid adjustments without stopping the machine or with minimal modifications during use. At the same time, after the lubrication system is shut down, the residual grease in the main oil passage and branch flow passage is prone to oxidation and solidification, forming sludge that blocks the precision flow passage. Existing technology relies on manual cleaning or passive oil drainage, which cannot actively remove residues. Long-term operation can easily lead to lubrication failure or even equipment damage. Therefore, those skilled in the art have provided a cartridge-type dynamic monitoring oil separator to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cartridge-type dynamic monitoring oil separator. The oil separator structure can adjust the length of the metering piston according to different oil output requirements, thereby inserting multiple oil separator structures with the same or different displacements to meet different oil output requirements. Depending on the application scenario, a single oil separator can be used independently, or multiple separators can be used in series or in parallel.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a plug-in type dynamic monitoring oil separation device, comprising a device body, an oil inlet at the center of the front end face of the device body, a main oil passage inside the rear end face of the device body, five pull slots arranged in a straight line on the upper end face of the device body, each of the five pull slots having an oil separation structure inside, a cleaning structure at the upper center of the rear end face of the device body, and a strip groove at the lower center of the front end face of the device body;

[0006] Taking the oil-separating structure at the front as an example, the oil-separating structure includes a metering component housing, which is located inside the front-end slot. A cylindrical groove is provided at the center of the inside of the metering component housing, and a circular groove is provided at the center of the lower inner wall of the cylindrical groove. The circular groove passes through the lower inner wall of the cylindrical groove and extends to the lower end face of the metering component housing. A switch valve is provided at the lower center of the inside of the cylindrical groove, and the switch valve is slidably connected to the circular groove. Circular holes are provided at the lower center of both sides of the switch valve. An annular groove is provided at the upper center of the inner wall of the cylindrical groove. A metering piston is slidably connected to the inner side of the annular groove. A second spring and a third spring are respectively connected to the upper end face of the metering piston and the upper end face of the switch valve and the upper inner wall of the cylindrical groove. Fixed seats are provided at the lower center of both inner walls of the cylindrical groove.

[0007] Through the above technical solution, lubricating grease enters the main body of the device from the oil inlet, and then flows through the main oil passage to multiple oil distribution structures. Under the push of oil pressure, the switch valve compresses the third spring and moves upward until a gap appears between the circular groove and the switch valve. The grease enters the cylindrical groove through the gap between the circular groove and the switch valve. At this time, the two fixed seats block the two circular holes to prevent grease from entering the switch valve. The grease entering the cylindrical groove pushes the metering piston to compress the second spring and move upward along the annular groove. When the metering piston reaches the top of the annular groove, the cylindrical groove is filled with grease, and the grease flow from the oil inlet stops. Upon entry, the oil pressure drops, and the switch valve descends under the push of the third spring. At this time, the gap between the circular groove and the switch valve is blocked by the two fixed seats, preventing them from blocking the two circular holes. The second spring pushes the metering piston down, allowing the grease inside the cylindrical groove to enter the switch valve through the two circular holes and flow out through the upper end of the metering housing, completing one oil discharge cycle. The oil distribution structure allows for adjustment of the metering piston length according to different oil discharge requirements, enabling the installation of multiple oil distribution structures with the same or different displacements to meet different oil discharge needs. Depending on the application scenario, a single oil distribution device can be used independently, or multiple devices can be used in series or parallel.

[0008] Furthermore, the cleaning structure includes a solenoid valve, which is located at the center of the rear end face of the main oil passage. A flow groove is provided at the center of the rear end face of the solenoid valve. An air pump is provided at the rear center of the upper end face of the main body of the device. A rectangular box is provided at the rear center of the inside of the strip groove. A cleaning groove is provided at the input end of the air pump. The cleaning groove passes through the flow groove and the upper end face of the rectangular box and extends to the inner wall of the upper rectangular box.

[0009] With the above technical solution, after the device is used, the solenoid valve is opened to control the air pump to start and adsorb the remaining grease inside the main oil passage through the flow channel. The grease enters the cleaning tank after passing through the solenoid valve and the flow channel and falls into the rectangular box. Through the negative pressure generated by the air pump in the cleaning structure, the residual grease in the main oil passage and each branch flow channel can be actively adsorbed and drawn into the rectangular box. This can effectively prevent the residual oil from remaining, solidifying or oxidizing and deteriorating in the system after shutdown, thereby preventing it from clogging the precision flow channel or contaminating the fresh grease supplied next time, and ensuring long-term operational reliability.

[0010] Furthermore, each of the inner sidewalls of the strip groove is provided with a sliding groove at the center rear, and each of the two sides of the rectangular box is provided with a sliding strip. The two sliding strips are slidably connected inside the two sliding grooves respectively. Each of the upper end faces of the two sliding strips is provided with a rectangular groove near the center. Each of the two rectangular grooves is provided with a first spring, and each of the upper end faces of the two first springs is provided with a trapezoidal block.

[0011] Through the above technical solution, the trapezoidal block and the first spring constitute a mechanical self-locking mechanism, which enables the cleaning module to be assembled and disassembled without the use of tools by simple push-in and pull-out actions, making it convenient to process the grease extracted from the inside of the rectangular box.

[0012] Furthermore, a connecting groove is provided at the lower center of the rear end face of the oil inlet;

[0013] The above technical solution allows for faster collection of grease through a connecting groove, facilitating cleaning.

[0014] Furthermore, a limiting ring is fitted on the upper part of the outer center of the switch valve;

[0015] The above technical solution prevents the switch valve from sliding out of the metering component housing by using a limit ring.

[0016] Furthermore, a magnet is provided at the center of the lower end face of the switch valve, and the magnet passes through the lower end face of the switch valve and is fixed inside the switch valve;

[0017] With the above technical solution, each time oil is dispensed, the magnet at the end of the switch valve disengages from the Hall detection board once, approaching and disengaging repeatedly. The control end can dynamically monitor the oil dispensing status of each oil outlet through the Hall effect. When valve jamming or other abnormal situations occur, and the Hall detection board cannot regularly monitor the movement of the magnet, a fault alarm will be triggered.

[0018] Furthermore, a Hall effect detection plate is provided inside the strip groove;

[0019] Through the above technical solutions, the Hall effect detection board detection method does not require physical contact with moving parts or complex mechanical linkage. The sensor itself is wear-free, has a long lifespan, and is completely sealed inside the device, unaffected by grease contamination, vibration, and moisture. It can still maintain extremely high monitoring reliability and accuracy in harsh industrial environments.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the cartridge-type dynamic monitoring oil separator can adjust the length of the metering piston according to different oil output requirements through the oil separator structure, thereby inserting multiple oil separator structures with the same or different displacements to meet different oil output requirements. Depending on different application scenarios, a single oil separator can be used independently, or multiple oil separators can be used in series or in parallel.

[0022] 2. In this utility model, by using the negative pressure generated by the air pump in the cleaning structure, the residual grease in the main oil passage and each branch flow passage can be actively adsorbed and drawn into the rectangular box. This can effectively prevent residual oil from remaining, solidifying or oxidizing and deteriorating in the system after shutdown, thereby preventing it from clogging the precision flow passage or contaminating the fresh grease supplied next time, and ensuring long-term operational reliability.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1-4 An embodiment of this utility model is provided: a plug-in dynamic monitoring oil separation device, including a device body 1, an oil inlet 2 at the center of the front end face of the device body 1, a main oil passage 3 inside the rear end face of the device body 1, five pull slots 4 arranged in a straight line on the upper end face of the device body 1, each of the five pull slots 4 having an oil separation structure 5 inside, a cleaning structure 6 at the upper center of the rear end face of the device body 1, and a strip groove 13 at the lower center of the front end face of the device body 1.

[0031] like Figure 3As shown, taking the front oil distribution structure 5 as an example, the oil distribution structure 5 includes a metering housing 501, which is located inside the front pull-out slot 4. A cylindrical groove 502 is provided at the center of the metering housing 501, and a circular groove 503 is provided at the center of the lower inner wall of the cylindrical groove 502. The circular groove 503 passes through the lower inner wall of the cylindrical groove 502 and extends to the lower end face of the metering housing 501. A switch valve 504 is provided at the lower center of the cylindrical groove 502, and the switch valve 504 is slidably connected to the circular groove 503. Circular holes 505 are provided at the lower center of both sides of the switch valve 504. A circular groove 506 is provided near the upper center of the side wall. A metering piston 507 is slidably connected to the inner side of the circular groove 506. A second spring 508 and a third spring 509 are respectively connected to the upper end face of the metering piston 507 and the upper end face of the switch valve 504 and the inner wall of the cylindrical groove 502. A fixed seat 510 is provided near the lower center of the two inner side walls of the cylindrical groove 502. The lubricating grease enters the device body 1 from the oil inlet 2 and then passes through the main oil passage 3 to multiple oil distribution structures 5. Under the push of oil pressure, the switch valve 504 squeezes the third spring 509 to move upward until a gap appears between the circular groove 503 and the switch valve 504, and the oil... Grease enters the cylindrical groove 502 through the gap between the circular groove 503 and the switch valve 504. At this time, the two fixed seats 510 block the two circular holes 505 to prevent grease from entering the switch valve 504. The grease entering the cylindrical groove 502 pushes the metering piston 507 to squeeze the second spring 508 and move it upward along the annular groove 506. When the metering piston 507 reaches the top of the annular groove 506, the cylindrical groove 502 is full of grease. At this time, the grease entering through the oil inlet 2 stops, the oil pressure drops, and the switch valve 504 descends under the push of the third spring 509. At this time, the circular groove 503 and the switch valve 504... The gap between valves 504 prevents the two fixed seats 510 from blocking the two round holes 505. The second spring 508 pushes the metering piston 507 down, allowing the grease inside the cylindrical groove 502 to enter the switch valve 504 through the two round holes 505. The grease then flows out through the upper end of the metering housing 501, completing one oil discharge cycle. The oil distribution structure 5 can adjust the length of the metering piston 507 according to different oil discharge requirements, thereby inserting multiple oil distribution structures 5 with the same or different displacements to meet different oil discharge requirements. Depending on the application scenario, a single oil distribution device can be used independently, or multiple devices can be used in series or in parallel.

[0032] like Figure 2As shown, the cleaning structure 6 includes a solenoid valve 601, which is located at the center of the rear end face of the main oil passage 3. A flow groove 602 is provided at the center of the rear end face of the solenoid valve 601. An air pump 603 is provided at the rear center of the upper end face of the main body 1. A rectangular box 604 is provided at the rear center of the inside of the strip groove 13. A cleaning groove 605 is provided at the input end of the air pump 603. The cleaning groove 605 passes through the flow groove 602 and the upper end face of the rectangular box 604 and extends to the inner wall of the rectangular box 604. After the device is used, the solenoid valve 601 is opened to control the air pump 603 to start. The system actively adsorbs the remaining grease inside the main oil passage 3 through the flow channel 602. After passing through the solenoid valve 601 and the flow channel 602, the grease enters the cleaning channel 605 and falls into the rectangular box 604. Through the negative pressure generated by the air pump 603 in the cleaning structure 6, the residual grease in the main oil passage 3 and each branch flow channel can be actively adsorbed and drawn into the rectangular box 604. This effectively prevents the residual oil from remaining, solidifying, or oxidizing and deteriorating in the system after shutdown, thereby preventing it from clogging the precision flow channel or contaminating the fresh grease supplied next time, and ensuring long-term operational reliability.

[0033] The inner sidewalls of the strip groove 13 are provided with sliding grooves 7 at the center rear. The rectangular box 604 is provided with sliding strips 8 on both sides. The two sliding strips 8 are slidably connected inside the two sliding grooves 7 respectively. The upper surface of the two sliding strips 8 is provided with rectangular grooves 9 near the center. The two rectangular grooves 9 are provided with first springs 10 inside. The upper surface of the two first springs 10 is provided with trapezoidal blocks 11. The trapezoidal blocks 11 and the first springs 10 form a mechanical self-locking mechanism, which allows the cleaning module to be installed and disassembled without the use of tools by simple pushing and pulling actions, which facilitates the treatment of grease extracted from the rectangular box 604.

[0034] A connecting groove 12 is provided at the lower center of the rear end face of the oil inlet 2. The connecting groove 12 facilitates the faster collection of grease by the cleaning structure 6.

[0035] A limit ring 511 is fitted on the upper part of the outer center of the switch valve 504 to prevent the switch valve 504 from sliding out of the metering housing 501.

[0036] A magnet 512 is provided at the center of the lower end face of the switch valve 504. The magnet 512 passes through the lower end face of the switch valve 504 and is fixed inside the switch valve 504. Each time oil is discharged, the magnet 512 at the end of the switch valve 504 disengages from the Hall detection plate 14 once. The process of approaching and disengaging repeats. The control end can dynamically monitor the oil discharge of each oil outlet through the Hall effect. When valve jamming or other abnormal conditions occur, and the Hall detection plate 14 cannot regularly monitor the movement of the magnet 512, a fault alarm is triggered.

[0037] The inside of the strip groove 13 is equipped with a Hall detection plate 14. The detection method of the Hall detection plate 14 does not require physical contact with moving parts or complex mechanical linkage. The sensor itself is wear-free, has a long lifespan, and is completely sealed inside the device, so it is not affected by grease contamination, vibration, or moisture. It can still maintain extremely high monitoring reliability and accuracy in harsh industrial environments.

[0038] Working principle: When the device is in use, the lubricating grease enters the body 1 of the device through the oil inlet 2, and then passes through the main oil passage 3 to multiple oil distribution structures 5. Under the push of oil pressure, the switch valve 504 squeezes the third spring 509 to move upward until a gap appears between the circular groove 503 and the switch valve 504. The grease enters the cylindrical groove 502 through the gap between the circular groove 503 and the switch valve 504. At this time, the two fixed seats 510 block the two circular holes 505 to prevent the grease from entering the switch valve 504. The grease that enters the cylindrical groove 502 pushes the metering piston 507 to squeeze the second spring 508 to move upward along the annular groove 506. When the metering piston 507 reaches the top of the annular groove 506, the cylindrical groove 502 is filled with grease.

[0039] At this point, the grease entering through the oil inlet 2 stops, the oil pressure drops, and the switch valve 504 descends under the push of the third spring 509. At this time, the gap between the circular groove 503 and the switch valve 504 is blocked by the two fixed seats 510, which cannot block the two circular holes 505. The second spring 508 pushes the metering piston 507 down, allowing the grease inside the cylindrical groove 502 to enter the switch valve 504 through the two circular holes 505 and flow out through the upper end of the metering housing 501, completing one oil discharge. The length of the metering piston 507 can be adjusted according to different oil discharge requirements through the oil distribution structure 5, so that multiple oil distribution structures 5 with the same or different displacements can be installed to meet different oil discharge requirements. Depending on different application scenarios, a single oil distribution device can be used independently, or multiple devices can be used in series or in parallel.

[0040] Each time oil is dispensed, the magnet 512 at the end of the switch valve 504 disengages from the Hall sensor plate 14 once, approaching and disengaging repeatedly. The control end can dynamically monitor the oil discharge from each outlet through the Hall sensor. When valve jamming or other abnormalities occur, and the Hall sensor plate 14 cannot regularly detect the movement of the magnet 512, a fault alarm is triggered. After the device is used, the solenoid valve 601 is opened to control the air pump 603 to start and adsorb the remaining grease inside the main oil passage 3 through the flow channel 602. The grease enters the cleaning channel 605 after passing through the solenoid valve 601 and the flow channel 602, and then falls into the rectangular box 604. Through the negative pressure generated by the air pump 603 in the cleaning structure 6, the residual grease in the main oil passage 3 and each branch flow channel can be actively adsorbed and drawn into the rectangular box 604. This can effectively prevent residual oil from remaining, solidifying, or oxidizing and deteriorating in the system after shutdown, thereby preventing it from clogging the precision flow channel or contaminating the fresh grease supplied next time, ensuring long-term operational reliability.

[0041] The equipment includes a control panel, which enables the equipment to be started and controlled through a human-machine interface and an electrical control system. Input signal processing converts the operator's instructions into electrical signals, and output signal transmission transmits control signals to various actuators to achieve equipment control. This is a commonly used technical solution in existing control systems, and will not be elaborated on further here.

[0042] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
